Laser interstitial thermal therapy (LITT) is gaining popularity in the treatment of
both primary and secondary intracranial tumors. The goal of LITT is to deliver thermal
energy in a predictable, controlled, and minimally invasive fashion. It can be particularly
valuable in patients with recurrent tumors who, due to previous radiation or surgery,
may have a potentially higher risk of wound breakdown or infection with repeat craniotomy.
Deep-seated lesions that are often inaccessible through open approaches (thalamus,
hypothalamus, mesial basal temporal lobe, brainstem) may also be suitable targets.
The experience and data published thus far on this modality is limited but growing.
This review highlights the use of LITT as a primary treatment method in a variety
of intracranial tumors, as well as its application as an adjunct to established surgical
techniques.
